Chiral Symmetry Breaking in a Soft-Wall Model of AdS/QCD
Joseph I. Kapusta, Thomas M. Kelley, Tony Gherghetta
TL;DR
This paper introduces a modified soft-wall AdS/QCD model that effectively incorporates chiral symmetry breaking, leading to mass spectra that align well with QCD resonances, by separating spontaneous and explicit breaking effects.
Contribution
It presents a novel approach using a modified dilaton profile and quartic scalar potential to model chiral symmetry breaking distinctly in the soft-wall AdS/QCD framework.
Findings
Mass spectra match experimental QCD resonances
Separation of spontaneous and explicit symmetry breaking
Improved modeling of chiral dynamics in AdS/QCD
Abstract
We incorporate chiral symmetry breaking in a soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one to separate the dependence on spontaneous and explicit chiral symmetry breaking. The resulting mass spectra in the scalar, vector and axial-vector sectors compares favorably with the respective QCD resonances.
